Why does Pig's dash end early if you hug a wall too close?

I've played a match as Pig just to test the new add-ons when I noticed a huge issue, in an attempt to catch up to survivors, i hug the wall close like they would. When I do this, it cancels out the dash entirely

The thing is, its not like it does the animation where you hit the wall, it just...ends early. Why? What's going on here?
